    Businesses want to execute an analytical job at scale in Hadoop, but different parts of that job are potential candidates for specific execution engines so that the job performs under optimal conditions. In addition, past engines such as classic Map Reduce are potentially giving way to new ones such as Spark. This talk will demonstrate how you can leverage the Datameer application to hide the complexity of choosing the right execution engine for an analytical job at scale in Hadoop, and how Spark fits into this context.

  • Hero Russian police officer executed by ISIS militants - but is defiant to the end

    The Ministry of Internal Affairs in the Russian Republic of Dagestan has announced that junior lieutenant of police Magomed Nurbagandov will be awarded posthumously for courage in the face of death. The policeman was killed on July 10, 2016 during a militants' attack on local residents resting on a picnic in the forest nearby Sergokala settlement. The gunmen shot to death Magomed and his cousin Abdurashid Nurbagandov having discovered their police identification cards. The militants' actions are perceived to be a deliberate revenge on law enforcement. The video of murder was uploaded on social media soon afterwards, but the militants had cut the episode showing the officer's courageous behavior from the footage. ​On August 7 the National Antiterrorism Committee (NAC) reported that six mil...

    A guillotine (/ˈɡɪlətiːn/; French: [ɡijɔtin]) is an apparatus designed for efficiently carrying out executions by beheading. The device consists of a tall, upright frame in which a weighted and angled blade is raised to the top and suspended. The condemned person is secured with stocks at the bottom of the frame, positioning the neck directly below the blade. The blade is then released, to fall swiftly and forcefully decapitating the victim with a single pass. The device is best known for its use in France, in particular during the French Revolution, where it was celebrated as the people's avenger by supporters of the Revolution and vilified as the pre-eminent symbol of the Reign of Terror by opponents.[1] The name dates from this period, but similar devices had been used elsewhere in Eur...

The militants' actions are perceived to be a deliberate revenge on law enforcement. The video of murder was uploaded on social media soon afterwards, but the militants had cut the episode showing the officer's courageous behavior from the footage. ​On August 7 the National Antiterrorism Committee (NAC) reported that six militants including the head of a local armed gang had been killed in Dagestan during two separate Special Forces raids. Three militants were neutralized in Izberbash and three more in Makhachkala. According to the NAC, the killed fighters were involved in terrorism-related crimes, including an August attack on road police and the July 10 shooting in which Nurbagandov was killed. The full version of the video was discovered in the cell phone that belonged to one of the militants. In the video one of the militants reads from Magomed Nurbagandov's police id card and asks if the card is his. Magomed, while being held at gunpoint, admits that the card belongs to him. The militant then demands that Magomed looks in the camera and tells his fellow police officers to abandon their duty. "Carry out your duty, brothers," Nurbagandov says looking straight in the camera, "What else you expect me to say?" He then asks the gunman. The officer was reportedly shot in his head a minute afterwards. Dagestan MIA said in a statement that Nurbagandov died a heroic death and that he will be recommended for a posthumous decoration.

Similarly to editors that share code completion or syntax highlighting, the development of advanced debuggers, animators, and others execution analysis tools shares common facilities, which should be reused among various DSMLs. In this tool demonstration paper, we present the execution framework offered by the GEMOC studio, an Eclipse-based language and modeling workbench. The framework provides a generic interface to plug in different execution engines associated to their specific metalanguages used to define the discrete-event operational semantics of DSMLs. It also integrates generic runtime services that are shared among the approaches used to implement the execution semantics, such as graphical animation or omniscient debugging.

This video explains the process behind a web browser. What happens when you enter a URL and press enter, and how does the browser know how to present the page to you? This is all explained, as well as all the components that make up a web browser. We use web browsers every day to display web pages, but have you ever wondered what is happening behind the scenes? This is the basic flow of viewing a web page: you send a request over the network to a server, it responds with a collection of web content as a response. Your browser interprets the content returned and displays the page. Let’s look at a high level structure of a browser and the components it uses to accomplish this: The user interface is what’s presented to the user to interact with. It displays to you the address bar, back and forward buttons and any other visual element you can interact with, such as tabs. A browser has a rendering engine that is responsible for displaying the visual representation of the webpage. Think of the rendering engine as a painter working on a blank canvas. It’s his responsibility to construct the page by applying the right structures and colours. The engine takes in HTML and CSS documents, then displays its interpretation of both. HTML exists to markup our content, and CSS is used to style and animate our content. The browser engine acts as a marshal who directs actions between the User Interface and the rendering engine, as well as external communication with servers. To receive content for a web page, the browser has to communicate over the network, asking for all the necessary images and documents that make up the page. You’ve probably encountered a situation where an image is missing on the page, this usually means the network failed to fetch the image from the server. ((demo ajax request in animation)) To apply interactive logic and functionality to our website, we rely on a programming language called JavaScript. The browser has no idea how to deal with JavaScript directly. It’s like a person who only knows Spanish, but is trying to listen to someone speaking Chinese. We need a way to translate the communication, and this is done with an interpreter. Browsers have their own JavaScript interpreters: Chakra is used by Microsoft Edge, SpiderMonkey for Firefox and V8 is used by Google Chrome. You also have something called data storage such as Cookies and Local Storage. This helps us retain state even when you refresh the page. You’ll find cookies are used to remember bits of information such as your name. The rendering engine can render images, videos, SVG files, audio files, but by default; displays HTML and XML documents; types of markup language. These documents as you can see are constructed of tags. Not all browsers use the same rendering engine. This is why you sometimes see inconsistencies with how things look from browser to browser. Chrome and Opera use an engine called Blink, Safari uses WebKit and Firefox uses Gecko. These engines have their own implementations of how to render the page, but all tend to follow the same flow. It’s the responsibility of the network layer to provide the rendering engine the requested document. Firstly, the rendering engine reads the HTML and constructs a DOM content tree, this stands for ‘Document Object Model’; an object representation of the HTML document. The DOM tree is made up of DOM nodes. Nodes can be images, text blocks, buttons or any other element. All the CSS styling associated with these nodes are parsed by the engine. Now with the styling information and visual instructions, a new tree can be created; the render tree. Once this has been constructed, it then goes through a layout process where each node is positioned on the screen with coordinates. The render tree is then traversed, with each node painted using the UI backend layer. The process happens so fast, you can’t see every node get rendered on the page, hence why the whole page’s entire content is visible when the page has finished loading. When the parsing process has finished, the browser will mark the document as interactive, allowing you; the user, to interact with the nodes on the page.

With Viz Trio's implementation of the new profile configuration, Viz Trio now supports forked execution by having more than one graphics render engine per channel. Simply put you can trigger the same scene on multiple render engines where one can act as your backup.
